Props goes out to Tim Verry for doing the research on the process of mining and helping to explain what Bitcoins are all about. Ken Addison did a great job doing through an alottment of graphics cards running our GUIMiner and getting the data you will see presented later. Scott Michaud helped with some graphics and imagery and I'm the monkey that just puts it all together at the end. ** Update 7/13/11 ** We recently wrote another piece on the cost of the power to run our Bitcoin mining operations used in this performance article. Based on the individual prices of electric in all 50 states of the US, we found that the cost of the power to run some cards exceeded the value of the Bitcoin currency based on today's exchange rates.
Bitcoin Mining Update: Power Usage Costs Across the United States.

Earlier this week we looked at Bitcoin mining performance across a large range of GPUs but we had many requests for estimates on the cost of the power to drive them.

At the time we were much more interested in the performance of these configurations but now that we have that information and we started to look at the potential profitability of doing something like this, look at the actual real-world cost of running a mining machine 24 hours a day, 7 days a week became much more important. This led us to today's update where we will talk about the average cost of power, and thus the average cost of running our 16 different configurations, in 50 different locations across the United States.

It will also be impossible to prove to anyone that you did not voluntarily transfer the money to your own anonymous account.
